LEWIS J. ATWOOD, OF WATERBURY, CONNECTICUT.

LAMP-BURNER.

EP-ECIFICAI'ION forming part of Letters Patent No. 327.054, datedSeptember 29, 1885.

Application filed September 10, 1884. (No model.)

To (LZZ whom it may concern.-

Be it known that I, LEWIs J. ATWOOD, of Waterbury, in the county of NewHaven and State of Connecticut, have invented an Improvement inLamp-Burners, of which the following is a specification.

In some lamps containing an air-distributer at the base of the deflectora cylinder has been used around the wick-tube and a sleeve sliding uponthe same, so that the chimney-holder and air'distributer can be lifted,the sleeve sliding upon the cylinder. In this lamp the sleeve may adhereto the cylinder, and when the friction is overcome the lifting motionmay be sudden. Inclines have been used withina circular air-distributer,but the same are liable to bend and become inefficient.

My improvement is made for raising the chimney-holder and deflector moreeasily and reliably, and 'for lessening the risk of the chimney-holderbeing separated from the base of the burner, or for entirely preventingsuch separation.

In the stationary guide surrounding the wick-tube I provide a screw orincline having one or two threads, and a nut or lifter around such guidehaving corresponding threads or inclines, and from this lifter there arearms extending to the chimney-holder and deflector, so that the chimneyand holder are raised bodily from the wick-tube by a partial rotation ofthe nut or lifter, and this can be very easily done by hand without riskof a sudden movement. The parts are arranged so that the arms do notinterfere with trimming or lighting the lamp.

In the drawings, Figure l is a vertical section of the lamp. Fig. 2shows the same slightly modified with the chimney-holder and deflectorlowered. Fig. 3is aside view of the burner, Fig. 2, with thechimney-holder and deflector partly raised; and Fig. 4 is a sectionalplan at the line as as, Fig. 2.

The screw-basea is adapted to fit the lampreservoir, and the wick-tube bis fastened to So, also, is the stationary guide 0,

the same. which is preferably of sheet metal, surrounding the wick-tube.It contains perforations,

especially in the upper part, so that air can' pass in through the sameand reach the base of the flame at the top of the wick-tube.

The inclines or threads in or upon the sta tionary guide are usuallyrolled into the same; but they may be made by slotsin the metal orotherwise.

The nut or lifter d surrounds the tube 0, and is provided with threadsor a pin fitting the threads or slots of the screw. The arms or supports6 extend outwardly and upwardly from the lifter (Z, and these armssupport the chimney-holder h, and the cone or deflector Z rests uponsuch chimney-holder.

It will now be understood that the inclines act to raise or depress thechimney-holder, and that the movement given to the chimneyholder is apartial rotation; hence the lifter is not liable to pass up too far orto become detached from the tubular screw, and by pro viding a stop atthe end of the screw-thread or incline the parts are held so that theycannot be separated.

It is usual to provide wick-raisers and a shaft, m, and as the liftershould be in the form of a cylinder around the stationary guide 0, inorder to steady the chimney'holder, it is preferable to notch the lifterwhere it passes the wick-raising shaft, so that such lifter may passdown into the screw-base and the burner be made as compact as possible.

The air-distributer o is provided for rendering the supply of airuniform. In Fig. 2 this air-distributer is made of one piece ofperforated metal, surrounding the wick-tube b, and attached to the topof the guide a, and it is of a size adapted to receive upon its edge theinterior portion of the chimney-holding ring it when the same is turneddown. When the chimney-holder is partially revolved, the inclines raisethe holder, so that access is given to the wick for trimming orlighting, and when so raised the arms are not in the way of thescissors, because they are opposite to the sides of the wick, as shown.

In Fig. l the air-distributer is shown as made in two parts. The portionabove and within the guide 0 is attached thereto and the other portion,0', is formed with the chimneyholder h. These parts come together whenthe chimney-holder is turned down, and usually there will be aforaminous casing, a, extending up from the base a, and upon the topedge of the casing the chimney-holder rests.

IOO

I do not herein claim a cylindrical guide within the burner and aroundthe wiclctube, nor a perforated air-distributer and inclines to act inraising or lowering the deflector and chimney-h older, as a burnerhaving such parts is shown in my application No. 142,553, filedSeptember 10, 1884.

I claim as my invention 1. The combination, with the burner-base,Wick-tube, deflector, and chimney-holder, of the stationary cylindricalguide around and adjacent to the Wick-tube, and having screwthreads orinclines, and a lifter around such guide acted upon by the inclines,arms connectin g the lifter with the chiinney-holder,and anair-distributer connected at the upper end of the gui de,-substantiallyas specified.

2. The combination, with the burner-base,

WlCktL1b8, deflector, and chimney-holder, of

the stationary cylindrical guide around and 20 adjacent to theWick-tube, and having screwthreads or inclines, and a lifter around suchguide acted upon by the inclines, arms connecting the lifter with thechimney-holder, an

air-distributer connected at the upper end of 2 Signed by me this 30thday of August, A. 30
